First book of the C.H.A.O.S. series
Colt McAlister has spent a day with real life aliens. Not that he remembers it. CHAOS (Central Headquarters Against the Occult and Supernatural) made sure of that when they invited Colt to a facility posing as a regular military academy to test his abilities and potential. Colt may have lived his whole life in ignorance and bliss, but when his parents were killed in a car accident, he got a tip from a stranger: Your parents were murdered. Your mom was about to expose the omnipotent Trident Industries' mind control scheme and so they had to get rid of her. And from that point on, Colt's normal life is turned upside down, when he discovers more than he ever wants to know about a secret organization and his grandpa's secret past.

I want to like this book, and when I read the first six chapters, I did kind of like it. A little thrown off because you were hit with the story without much explanation, but kids training to be secret agents battling extraterrestrials? Nothing super original, but it can be fun. The story then took a turn once the first CHAOS scene is over, and Colt and the readers both have to go through a lot of secrecy from all the other characters, and impatience started to seep in. There was too much conspiracy talk and the escaping from evil guys scenes got a bit repetitive. Some of the alien creatures and the high-tech weapons and vehicles were pretty cool, and there were some interesting story threads, but not enough to hold my attention. Danielle and Oz, the other two major characters in the book, are much more personable than Colt, which doesn't help either. Invasion did receive positive reviews, and a sequel is coming out in January 2012, so this may be a good one to include in your teen collection for your sci-fi readers.
